MACHINE FOR SLICING POTATOES.

T 0 all whom it may concern:

Be it known that I, JOHN H. DOAK, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Machines for Slicing Potatoes, of which the following is a specification.

This invention relates to a machine for cutting potatoes and the like into slices, and is especially adapted for slicing boiled potatoes. j

Boiled potatoes have been difiicult to shoe by machine, because they crumble under pressure. It is the primary object of my 1nvent-ion to provide a machine in which the potatoes are cut into a number of shoes at one time, and whereby no auxiliary holding mechanism is required. Another object of this invention is to provide a slicmg machine, which is simple, compact and durable in structure, and which is easy to manipulate.

These objects will be more fully understood as Will also other objects and corresponding accomplishments of my invention from the following detailed descriptlon of a preferred embodiment thereof. For the purpose of this description reference 1s had to the accompanying drawing, in which:

Figure 1 is a side elevation of a slicer; Fig. 2 is a plan view, fragments of the end covers being broken away to better show the blade suspension construction; Fig. 3 is an enlarged section taken on the line 3-8 of Fig. 2, alportion of the slicing blade being shown broken; and Fig. A is a section taken on the line 4l4: of Fig. 1.

Referring more particularly to the drawing, the base is indicated by A and the slicing frame by B. The frame is pivotally connected to the base and carries knife blades. The potatoes to be sliced are placed upon the base board and the frame swung down thereover.

The base A comprises a base board 5 having grooves parallel to one another and eX- tending longitudinally of the table. Each groove is designed to receive a slicmg blade. The base board 5 has an extension 7. Beyond the grooved portion, the upper surface of the extension is about or a little below the level of the bottoms of the grooves. The extension 7 is preferably covered with a metallic sheet such as aluminum plate.

Specification of Letters Patent.

Patented Nov. 4, 1919.

Application filed March 24, 1919. Serial No. 284.641.

Supporting the base board are legs 8. Side guard boards formed preferably of metal and attached to the base board are indicated by 9 and 1 0. A tie rod 11 braces the guard boards. At the rear of the base board and attached to the sides thereof are hinge brackets, one of which is indicated by 12 in Fig. 1. These brackets serve as supportsin which the slicing frame is journaled. The slicing frame comprises a rectangular frame let preferably formed of a cylindrical rod bent to produce the rectangular shape. Spanning the rectangular frame adjacent the rear thereof is a tube '15 best shown in Figs; 2 and 3. Tube 15 is held in position by a loop 16 passing around the rear bar of the frame 14: and the tube 15. This loop 16 is preferably a metallic tube which has been flattened. Adjacent the forward end of the frame and spanning the same is a tube 17 similar to tube 15. A loop 18 passes over tube 17 and over a rod 19. Loop 16 and tube 15 have registering slits to recelve slicing blades 20. Within the tube 15 is a rod 21 which is passed through holes formed in the blades 20. When tension is placed upon the slicing blades, the rod 21 rests against the tube 15 and ties the blade to the tube. A similar rod 22 is disposed within tube 17 and passes through openings in the other end of the slicing blades. A number of openings are formed in the loop 18 through which pass the eyes of turn buckles 23. The eyes are hooked over the rod 19. The other eyes of the turn buckles are engaged with rings 24 mounted upon the forward bar of frame 14. It is obvious that upon tightening the turn buckles 23 the blades 20 are firmly held in position under tension. For the purpose of more securely holding the blades in position, straps, one of which is indicated by 25 in Fig. 2 are attached to the loop 18 and pass over the side bar of the frame 14. The turn buckles, loop and suspension means at the forward end are preferably covered by a cap 26', which forms a shield.

The tube 15 adjacent the rear end of the frame is journaled in the brackets 12 so that it may swing with relation to the base board. Upstanding from the slicing frame is a back guard board 27 preferably of metal suitably braced by rod 28. For convenience in swinging the slicing frame, a handle 29 is secured to the forward end. of the base board.

Suppose it is desired to slice some boiled potatoes for frying, the slicing frame 26 v is s'vvung upwardly away from the base board. The potatoes are now placed upon the base board, and the slicing frame swung downwardly until the blades rest in the grooves 6. The potatoes Will have been sliced each intoa number of pieces. The blades in their passage tl'irou'gh a single potato each assist other blades in holding the potato as Well as cutting the same. In this way crumbling of the potato is avoided. After the potatoes have been sliced, the blades being "within the grooves, the slicer may be tilted to discharge the sliced potatoes at the fori vard end.

hat I claim is: In a potato slicer, thecombination of a 'as'e having a plurality of slots in the face thereof, side guards upstanding from said base and forming therewith a trough, a slicing frame pivotally mounted on said base and movable outside of said guards, said frame having slicing blades suspended therein so as to be swung entirely into and out of said slots, and a back guard board on said frame for closing s'a'id trough at the rear. p

In Witness that I claim the foregoing I have hereunto subscribed my name this lath day of Maroh, 191 9.
